Myocardial bridges are not serious if controlled and may be serious if not treated aggressively. Myocardial bridging is a congenital variant in which abnormally developed myocardial fibers cover part of a coronary artery. Clinically, drugs such as metoprolol tartrate and bisoprolol are often used to reduce myocardial contractility and decrease the compressive effect on blood vessels during myocardial contraction in order to alleviate the symptoms of myocardial ischemia, and coronary artery bypass grafting surgery can also be performed for treatment. If the patient is actively treated and the condition is under control, myocardial ischemia caused by myocardial bridges will not get worse. Without active treatment, abnormal myocardial fibers continue to compress the coronary arteries, resulting in aberrations in the coronary arteries, causing insufficient blood supply to the heart and symptoms such as angina pectoris and arrhythmia. Therefore without active treatment it may be serious. Patients with myocardial bridge should actively cooperate with the treatment under the doctor’s advice, take medication on time and in accordance with the dosage, and undergo regular review to ensure that their condition is stable.
